To all 1071/0771/ t party 00h/007%:

l Beitknown that I, EDWIN BROWN, a citizen of the United States,residing at Vorcester, in the county of Vorcester and State ofMassachusetts, have invented a new and useful Card-Clothing, of whichthe following is a specification.

This invention relates particularly to an improved backing forcard-clothing; and the 1o especial object of this invention is toprovide a strong, inexpensive, and uniform backing which will be moredurable and reliable than composite backings heretofore employed,because no rubber is used therein. To this end this invention consistsof the backing for card-clothing, as hereinafter described, and moreparticularly pointed outl in the claims at the end of thisspecification.

In the accompanying drawings, Figure lis a perspective view of a backingfor cardclothing, the dierent layers thereof being turned to show theirconstruction. Fig. 2 is a sectional view of a complete piece of cardclothing constructed according to this inven- 2 5 tion. Fig. 3 is asectional view of one of the intermediate cloth-layers, and Fig. 4 is asectional viewr of one of the outer cloth-layers.

In the manufacture of card-clothing leather backings or expensive clothbackin gs are usually employed.

To make good leather card-clothing, it is necessary to employ especiallyexpensive high-gradeleather- The objections to the use of leather arisesprincipally from its Want of uniformity and elasticity. A strip ofleather will be finer or coarser grained and Will stretch more or less,according to the part of the animal from which it is taken.

The disadvantages of the use of leather as a backing for card-clothinghave been recognized for many years, and attempts have been made toprovide a composite backing which will be equally efficient and which atthe same time may be made more uniform and at a less cost than a leatherbacking. A number of these composite backings have been made out of anumber of layers of cotton cloth; but heretofore when several layers ofcotton cloth have been employed it has al- Ways been found necessary touse rubberecement for uniting the layers, because ordinary cotton clothis sti and unyielding, and if the layers are glued together' withoilglue the backing would not possess the requisite degree ofiiexibility and the several layers could also be readily pulled apart.The use of rubber-cement and, in fact, any composition containing rubberhas proven to be unsatisfactory because of variations under differentat` mospheric conditions and because rubber in 6o any form deterioratesand perishes quickly, especially if oil is dropped onto or is broughtinto contact with or near the same.

The especial object of the present invention is therefore to provide abacking for cardclothing in which a plurality of layers of cotton clothare so formed and united as to constitute a backing having the requisitedegree of flexibility and which can be produced Without the use ofrubber. To accomplish 7o this object, a backing for card-clothingconstructed according to thisinvention comprises a plurality of layersof cotton cloth having one or both sides napped, so that the backingwill have the requisite degree of exibility and the several layersthereof When cemented together With oil-cement Will adhere, so that theycannot be readily pulled apart.

Referring to the drawings and in detail, a backing for cardclothing asherein illus- 8o trated comprises a body portion A, of firm cloth of anydescription. On top of the body portion A are a plurality ofintermediate layers C of cotton cloth, having one and preferably bothfaces thereof napped or roughened, as shown most clearly in Fig. 3. Ontop of the intermediate layers C is a top layer B, having its inner facenapped or roughened, as shown in Fig. 4, and cemented on the bottom ofthe body portion A is abottom facing 9o B similar to the top layer. Theseveral lay-V ers of this backing for card-clothing are prefL ablyunited by oil-cement, and by napping or roughing the faces of theseveral layers of cotton cloth employed I not only produce a backinghaving the requisite amount of flexi bility, but I also provide forsecuring the layers together Without the use of rubber. The cement whichI have employed to best ad; vantage for securing the severalcottonecloth Ico' layers together consists, essentially, of a solutionof the best quality of glue in linseedoil. In some instances I havefound it desirable to thin or reduce this cement by various quick-dryingliquids, and the proportions and ingredients of my cementing liquids mayof course be considerably varied. In the use of the backing Wires D maybe set therein in the ordinary manner to complete the card-clothing, asshown in Fig. 2.

I am aware that changes may be made in constructing my backing forcard-clothing by those who are skilled in the art without departing fromthe scope of my invention as expressed in the claims. For example, thenumber of layers of cotton clot-h employed or their relative arrangementmay be widely Varied, or the intermediate layers may be napped orToughened on one face only. I do not Wish, therefore, to be limited tothe construction herein shown; but

W'hat I do claim, and desire to secure by Letters Patent of the UnitedStates, is

1. As an article of manufacture, a backing for card-clothing comprisinga plurality of napped on both faces, the several layers be-.

ing joined together by oil-cement, and Wires set into said backing,substantially as described.

In testimony Whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.

EDWIN BROWN.
